我只是想试一试新框架Padrino。我按照这里给出的步骤。我一直在运行 rake 任务。我使用 Mysql 作为我的数据库。我使用命令创建了项目。
padrino g project sample_blog -t shoulda -e haml -c sass -s jquery -d activerecord -a mysql padrino g admin
我按顺序拥有所有依赖项，我进行了Bundle install以确保它。然后，当我运行 rake 任务时，我得到了这个错误。
$ padrino rake ar:create --trace
=> 执行 Rake ar:create --trace ...
** Invoke ar:create (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute ar:create
rake aborted ！
